ALEXANDER RANDOL, OF TARENTU-M, ASSIGNOR OF SIX-TENTHS TO GEORGE S.MOKEE, OF ALLEGHENY CITY, AND JOHN M. ARNOLD, OF PITTSBURG,

PENNSYLVANIA GAS-BURNING APPARATUS.

{ SPECIFICATION forming part of Letters Patent N 0. 316,059, dated April21, 1885.

Application filed December 26, 1884. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER RANDoL,

of Tarentum, Pennsylvania, have invented a new and useful Improvement inGas-Burning 5 Apparatus, which improvement is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide an improved burner for usingnatural or manufactured gas in connection with the furnace.

In the accompanying drawings, Figure 1 is a longitudinal section ofburner apparatus as r 5 attached to the furnace combustion-chamber. Fig.2 is a cross-section taken at w w, and Fig.

3 is a cross-section taken at y y.

A represents a common gas-pipe. a is a regulating-valve. a is the burnerproper, be- 20 ing secured to the pipeA at a and to thecombustion-chamber B at (L The gas passes through the pipe A into theburner a, and on into the chamber B, as seen in Fig. 1. The gas onentering the chamber 2 5 B is ignited, and then comes in contact withjets of air admitted through the perforations b b in the chamber B. Thisair being admitted in this way and at this point thoroughly mixes withthe gas, thus contributing to a more 0 perfect combustion than isusually attained. The flame thus created passes on out of the chamber Binto the larger combustion-chamber O, in which the combustion is carriedon and accelerated by the admission of air at the 5 end of this chamber0 at c c, this being regulated by any usual regulator device.

The chambers B and C are made of any good refractory material, such asfire-clay tile or metallic pipe.

The chamber B is held in position about the 0 center of the chamber 0 bya series of adjustable supporting-screws, c 0. These screws '0 arearranged in series bearing against the cylindrical chamber B at threeequidistant points of its circuit in cross-section. By means of 43 thema lateral adjustment of said chamber may be effected as well as alongitudinal adjustment.

The end of the chamber 0 will be closed, (the end at 0 c,) having onlyholes for admitting the air, as mentioned before.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The chambers B and O, in combination with 5 5 burner a, which dischargesinto the former, and the screws 0, which pass inward through saidchamber 0, and bear against said chamber B at different points of itsperiphery in cross-section, to allow lateral as well as longitudinal ad-60 justment, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I hereto set myhand in presence of two witnesses.
